9 Claims.

This invention relates to containers for the packing or packaging ofcommodities, and pertains particularly to containers of the type whichmay be manufactured and shipped in knocked-down or substantially atcondition and may be set up at the point of use. While not limited tosuch, it finds particular utility in the construction of such containersfrom paper board or the like.

A general object of the invention is the provision of an improvedcontainer structure which may` be completely fabricated at the factory,packed and shipped in knock-down condition in a space which representsonly a small fraction of its volumetric capacity, which may be readilyand quickly set up or assembled at the place where it is to be used orfilled; which when so set up will constitute a secure, tight and strongcontainer and protection for its contents.

A particular object of the invention is the provision of a containerstructure possessing the above mentioned characteristics and which maybe manufactured at low cost.

Another object is the provision of such a container structure whereinthe two end closures are interchangeable.

Other and further objects will be pointed out or indicated hereinafteror will be apparent to one skilled in the art upon an understanding ofthe invention or its employment in use.

For the purpose of aiding in a disclosure of the invention, we show inthe accompanying drawing forming a part of this specification, andherein- 'after described, certain structural embodiments of it, but itis to be understood that these are presented for purpose of illustrationonly, as we are aware that' the invention may be embodied in otherforms. Hence the present description and disclosure of the specificexamples are not to be construed in any fashion calculated to limit theappended claims short of the true and most comprehensive scope of theinvention in the art.

In the drawing, y Fig. 1 is a perspective view illustrating a cap or endclosure for a container, parts being unfolded for the purpose of moreclearly showing the construction; K l

Fig. 2 is a part elevational and part sectional elevational View of anend portion. of a container, same serving to illustrate the constructionand assembled relationship of a cap or end closure and a tubular bodyportion; and

Fig. 3 is a perspective view, partly in elevational section,illustrating the construction and assembled relationship of a cap or endclosure and a somewhat different tubular body portion.

(Cl. 22S-5.5)

The nature of the invention will be most quickly ascertained from theillustrative embodiments shown in the drawing, which will now bedescribed. In the form shown, the container comprises a tubular trunk-orbody portion and two 5 caps or end closures, the latter being identicalor interchangeable, although it is to be understood that suchinterchangeability is not an essential feature of the invention.

The cap or end closure is shown in Fig. 1, in a l0 partly disassembledcondition. It is formed of a sheet I0 of paper board or the like, which,for a cylindrical or frusto-conical container, is of approximatelycircular outline, its outer portion beingslotted to form tongues II,which extend in 15 generally radial directions from its central or bodyportion. A thin hoop I2, which may be made of paper board, rests uponthe end sheet I0 in concentric relationship therewith, and the tonguesII, which are spaced from one another 20 by flaring notches, are bent upagainst the outer s ide of the hoop I2, over the rim thereof anddownwardly against the inner side of the hoop. The intervening notchesare so proportioned that when thus folded about the hoop, the tongues 25abut one another margin to margin. Preferably the tongues are fixedindividually to the outer and inner sides of the hoop by adhesive,although such fastening of the tongues is not essential. The endportions of the tongues, designated IIa, 30 which rest against theinner. side of the hoop, form an inwardly projecting ledge or shoulder,as shown in Fig. 2.

The container side or trunk member I4 is a tube or sleeve of exiblematerial, such as paper 35 board, and preferably is formed withlongitudi' nal creases I4, as in accordance with the disclosure in ourco-pending applicationA Serial No. 644,809, filed November 29, 1932. Itis adapted to be collapsed to substantially flat condition, or 40 set upin a substantially cylindrical form.

To provide for the connection of the end closure with it, the trunkmember may be provided at its end with a narrow peripheral strip I5,secured by adhesive to its outer side and pro- 45 jecting therefrom as ashoulder or ledge. The width of this strip I5 is slightly less than thespace between the margin of the ledge IIa and the end sheet Ill of theend closure. The external diameter across the strip I5 being somewhatgreater than the internal diameter across the ledge IIB, and the end ofthe trunk member being inserted within the cap or end closure, themargins of the strip I5 and ledge IIa will be brought to an overlappingrelationship, as illus- 55 trated in Fig. 2, and an effective'connectionof the end closure to the trunk member provided. It is to be observedthat this method of connection may be employed at either or both the topand bottom ends of the container. It is apparent also that the hoop I2may be either of cylindrical form, or of frusto-conic form aring towardthe end sheet I0.

In Fig. 3 is illustrated another arrangement for connection of the endAclosure to the trunk member, which arrangement may be mostadvantageously employed for the connection of the bottom end closure. Itwill be seen that the tubular trunk member I4 is provided at its lowerend with a plurality of tongues I6 and short longitudinal slots I'I.Such construction of the trunk member is described in more detail in theapplication identified above. An end closure of the above describedconstruction being provided, the trunk member is inserted within thehoop, the tongues I6 being turned radially inward so as to rest upon theinner surface ofthe end sheet I D. Then a wedging disk I8, of a diametersomewhat greater than the internal diameter of the trunk member, ispressed down into the latter and within the compass of the hoop of theend closure. When it passes the ledge I Ia, the wedging disk I8 willspring the portions of the trunk member wall between the slots I'Ioutwardly to positions below the ledge, and hold them securely wedged inthat location against the inner side of the hoop I2. So assembled, theledge I la, overhanging .the outwardly wedged portions of the trunkmember wall, will hold the trunk member against withdrawal from thehoop.

It will be appreciated from the foregoing that identical end closuresmay be used to form a bottom construction such as illustrated in Fig. 3and either a bottom or top construction as illustrated in Fig. 2.

Depending on the manner in which they are folded and secured, theportions of the tongues at the outer side of the hoop member may eitherconform to the curvature thereof, or may be straight, or more nearlystraight in the circumferential direction. Consequently, the peripheralcontour of the end closure may be either approximately circular orpolyhedral. The hoop member holds the tongues against separating orflaring, and the tongues, by virtue of their marginal abutment one withanother, reinforce the hoop member against collapsing.

The construction provides a secure and strong container which may bemanufactured economically, packed for shipment in a space which is quitesmall as compared to its capacity, and which may be set up very easilyat the place where it is to be illed.

What we claim is:

l. In a container, an end closure comprising a hoop member and an endsheet covering and closing one end thereof and having marginal tonguesfolded across the outer side and margin of the hoop member and withtheir extremities turned in against the 'inner side thereof, and aexible tubular trunk member having its end portion extending within thehoop member and provided with a peripheral shoulder interposed betweenthe end sheet and the in-turned extremi- 'ties of the tongues.

2. An end closure for a container, comprising 10 a hoop member, and anend sheet having a body portion covering and closing one end thereof andhaving marginal tongues folded across the outer side andmargin of thehoop member and with their extremities turned inwardly against the innerside thereof and terminating at a distance from the body portion of theend sheet to afford an intervening channel.

3. An end closure as specified in claim 2 and wherein said tongues aresecured individually to the hoop member.

4. An end closure as specified in claim 2 and wherein said tongues aredisposed in marginal abutment with one another and are secured to thehoop member.

5. A container comprising the combination with an end closure as speciedin claim 2, of a flexible tubular trunk member having an end portionextending within said hoop member, and a wedging disk holding portionsof the trunk member wedged outwardly between the body portion of the endsheet and the extremities .if the tongues.

6. An end closure as specified in claim 2 and wherein the peripheralcontour afforded by the tongues about the hoop member is approximatelycircular.

7. An end closure as specified in claim 2 andv wherein the contourafforded by the tongues about the hoop member is polyhedral.

8. In a container, the combination with a tubular trunk member having anoutwardly jutting peripheral portion adjacent its end, of an end closurecomprising an end sheet having a body portion covering the end of thetrunk member and marginal tongues bent angularly from the plane of thebody portion and their ends turned reversely so as to extend toward thebody portion but terminating at a distance therefrom to afford anintervening channel, and a hoop member enfolded by said tongues andholding them against flexion away from the trunk member, the outwardlyjutting portion of the trunk member being disposed in said channel.

9. In a container, a construction as specified in claim 8 and whereinthe lateral margins of the juxtaposed tongues are contiguous to oneanother.
